Dasineura urnicola

Contarinia verrucicola

Asphondylia recondita

Galls on the upper side of the leaves of Urtica gracilis, either on the midrib, or, more often, on the lateral veins. Urn-shaped (I mean the shape produced by cutting off the
smaller end of a slender pear) up to 3 m. m. high, subsessile (that is, connected by a very small surface with the leaf), pale green, semi-transparent, succulent gall, bearing a short style or nipple at the upper, truncate end. Inside, the larva of a Cccidomyia. Lake George, July, 1863 ; Trenton Falls, July, 1874 ; not uncommon, but not in large numbers. Each leaf bears one, sometimes two galls, seldom more.

Cecidomyia (tiliae) verrucicola, n. sp. Wart-shaped, round, pale green galls, 3 — 4 millim. in diameter, projecting on the upper and underside of the leaves of the linden. They occur between the ribs and veins and often upon them. In autumn they become brown, hard and woody, and spring open on the underside, a circular piece detaching itself and either falling to the ground, or remaining fastened to the gall by a small portion of its circumference, in the shape of a lid. Inside of the gall, when green, there is a low-roofed cavity, containing a white larva, with a distinct breast bone, heart-shaped anteriorly, and ending in an elongate point posteriorly. The dry galls are empty. I found them common on Goat Island (Niagara Falls), on the hills near West Point, N. Y., in Cambridge, Mass., etc., in August and September, on the young shrubs of the linden.

*Asphondylia* (asteris) *recondita*, n. sp. 
Deformed terminal buds on the principal and the lateral branches of *Aster patens*. These galls consist merely in an arrest of growth and consequent accumulation of leaves, forming a bud-like body up to 10 or 15 m. m. in length. Inside I found pupae which their structure proves to be those of *Asphondylia*...did not succeed in rearing the fly.
